AT&T hotspots are now offering free Wifi access to iPhone users. Barnes and Noble, Starbucks, and AT&T’s other Wifi hotspot locations are now offering iPhone users a custom portal to access free Wifi. All you have to do is input your iPhone’s phone number and you can access the Wifi for free.

AT&T recently took over as the provider of Wifi hotspots from the previous provider of T-Mobile for 7,000+ Starbucks nationwide. AT&T had already announced that current AT&T broadband customers would also have free access and would “soon extend the benefits of Wifi at Starbucks to its wireless customers,” but up until now no signs of it had come about.

What’s great about this news is that if you have an iPhone but would also like to access the Wifi for free on your notebook, you can change the user agent of your browser to the iPhone’s User Agent and by inputing a valid iPhone phone number you will also get access on your notebook.
